1. A process for catalytic cracking of hydrocarbon oils, comprising the step of contacting a hydrocarbon oil feedstock with a catalytic cracking catalyst for reaction in a reactor comprising a dilute-phase transport fluidized bed and a fast fluidized bed connected in series, wherein the fast fluidized bed comprises a full dense-phase reaction zone that has an axial solid fraction ε of the catalyst within a range of about 0.1 to about 0.2 from bottom to top.
